The intermediate gear joumziied an a silml Y9 which pivotally cm'mec'ts the iBElCiS 0i. two radius arms Lessons 80 end 81 that are journeled on the shafts .o6 snd'73, respectively. With this arrange ment, the shafts 73 and 66 can be moved toward and from 6 ch other without in any Way disturbing the operative connection be-' tween said shafts.

. y The rolls 2, i'ond 6 are idler rolls. Each adjustment of the yoke for each lower roli d u 1S efiected by means of ad usting screw formed on the home and has screw which is"screw-threoded through an arm 8% rigidly secured to the girder 22, each screw 85 resting against the lower end of the stern 83 so that by. turning the screw one wuy'or the other the oke 82 con be raised and lowered. For a justing each yoke 82 for the upper roli on adjusting s ew s? i, employed which is suspended in i erin 88 threaded engagement with s portion 89 of; the stem. in the case of the upper rolls the yokes are suspended on the adjusting screws 87, while in the case of the,lower yo cos, they are sup ported on said adjusting screws.

The idler roils 8 which are errenged to rotate about vertical axes pivoteiiy nounted; on blocks 90 which slidebly mounted in ways in o y reshaped sop-port 91. This eke-shaped support 91 ES siistanned on t e frame in a manner similar to the lower yokes 82, tha;tis, it loss is stem 993 which is verticslly odj'usteble in ways formed in ii bracket 93, and it is retained in its verticaiiy-sdjusted position by an :idju'sting screw 94 which engages the lower end of the stem and is screwthreeded through a bracket arm 95. The blocks'90 are adjustable toward and from each other by means of adjusting screws 96 which have screw-threaded engagement with the ears 9'? of the yoke and impinge against the outer "iooesof the blocks 90.

The lost rolls 9 of the serieslere positively driven, and inasmuch as they operate on the outside of the tube, it is necessary thst the should be capable of adjustment toward on from each other, so as to ecconunodete tubes ofdifierent diameter, and this requires a different adjustmenti'rom that provided inountedon the shaft 38. The gear turn meshes with a gear 10; which is mounted on ev shaft that is journeled in two bracket members or arms 103 that are pivotsiiy mounted on the upper shefi 104 which can rise the upper roll 9. This shaft 1.04 hes e gear 10;: thereon which meshes with the gear 1.02. 106 a. frame which is secured to the two arms or brackets 103 and which ties them together thereby making a rigid structure.

The lower roli 9 is positively driven from its'cross-shnit 6% and the gearing above de scribed provides for positively driving the upper roll?) from the lower roll and st the some speed as said lower roll. Qiie nrrns 103 and 101 form a link connection which ollcovs the shafts i0 5 and 38 to be moved toward and from each other without disturbing the driving connection between the two,

duced into the machine or at some point during its passage through the machine, end i have accordingly provided a construction whereby such support may. be placed at any desired point. The brackets or housings 84: in which the yoke/s 82 are supportedere each formed are pert of a yoke-shaped costing 107 W ci embraces the lower rder 22 and is C01 oected to e cross room; a ports the besring (i i. These ro -embers 10'? 1&8 E-o'rin o supporting street which ontireiy encircies the girder and ishes the support for the bearings 6i e the yokes 82'. Encii of these costings 107' is provided with an extension. 109 having guidewnys 110 odepted to support the stern iii of a rest 112. These can be edjns verticallyond ere retsined in their ad in d position by clei'nping screws 113. Since each of the memhersii is provided with the guidewey 110 it is possible to piece e restfilQ at any point desired along the length or the ironic. The extension 109 is preferably made with s guidewey 110 on each side thereof so that it may support tworests, as shown the ieif't in Fig. l

The machine shown in "Fig. i. has two guiding rolls 11 i situated in advance oi the first pair of roiis i. and which oil-operate with the two rests 112 to guide the skeip it is fed into the machine.

it will be noticed that the frame of the machine is reietively simple in design, it comprising the upper and lower girders 22, 2-3 on wi hore sustained e piurelity of similar s 'i'ictures 107, 508 that csrry the idler rolls and the cross-shafts for the positively-driven rolis other dupiicate sup portingstruetures 43, 4-1, which sustain the bearings for the positively-driven Fin-h these supporting structures 10?, l
